This invention relates to an auxiliary op erating device for stapling machlnes', tag aflixing machines and simllar devices, and

has for an object to provide an operating device of simple and easily manipulated construction which may be usedon a desk or table "inanofiice, jor secured toa bench in a factory, as a separate. operating means for operating small machines u'sedin-the office or factory eyelet or riveting machines, dating machines and the like, which are ordinarily sold as I complete units and include a hand operating means. These machines are sold complete and in a large percentage ofoflices may be operated onlya few times a. day,- but if they are operated more or less continuously or a large number of tlmesthey may tire the hand of the operator, and it is desirable toprovide some additional operating means which will be less tiring. It is, therefore, an object of;

thisiinvention to provide a separateror additionaloperating means for these types of machines into which the machines may be placed as a whole and operated by hand, foot pedalor even power means, without the necessity of making any mechanical connec tions,.or without in any wayinterfe'ringwith l easy portability of the machine for use in different parts of the ofii'c'e or factory, and with out interfering with its use in theordinary manner as a handmachine. i Withthe foregoing and other objects in View, I have devised one form of the invention 'as illustrated in thei accompanying drawing forming a part of this specification. Inthis drawing e L IFig: 1 is aside elevation of the device a .40 showing astapling machine in position to be operated thereby and portions of the base broken away to more'clearly show the construction. I i I r Fig. 2 is a top plan view thereof, andpowerdrive which may be employed if desired. i H i The device illustrated comprises a base 0 support 10 of any. suitable material, such as wood which may rest on or be secured to the top of a table, desk or bench,11.. Mounted particularly of the typeof stapling machines, tagfaffixing machines, numbering machines,

.For the drawing these openings are arranged and spaced to correspond with thefeetpof the on this base or support is a bracket 12 which may be secured thereto by any'suitable means, such 1 as screws 13. This bracket has laterally extending, arms Hand 15 forming a pivotal support 16 for an operatinglever 17.

The bracket also includes an upright eXtension 18 carrying a grooved guide pulley 19. As illustrated in the drawing the machine to be operated is one ofthe standard types i V of stapling machines comprising a base 20 to which is pivotally mountedlat 21 a housing 'The'base carries an anvil 23 cooperating with a vertically reciprocating'plunger 24 mounted in the housing for setting the in dividual staples through sheets of paper or other articles in the well known manner. In these machines which are ordinarily used for office work. theplunger carries a hand knob 25 by which iti's operated by being pressed downwardly through pressure of the hand on. this knob. 3 Also ordinarily the front end of the housing is normally held in elevated position for easy insertion of the work on the anvilby any suitable means, i

such as a spring 26, These machines ordinarily liavef rubber or fibre feet-i 27- on the under side? of the base so as notto mar the top oftheffurniture, and I utiliz'e theseelementsas' a means for properly positioning and holding the machine in the operating device. :F or this purpose the baselO is provided withlopenings or recesses 28 suitably spaced and positioned to receive the A feet of the different machines which is intended. to

be operated and cooperate with these feet to hold the various machines in proper position. example, in; the arrangement" shown in particular type of stapling machine shown but it will be understood thebase will be provided with other similar recesses for the feet of shorter machines or of the different machines to'be used. a

:The lever 17 extends forwardly from its .9

pivot overthe knob 25 and carries a roller29 adapted to engage the top of this knob. It

will be apparent that depression of the forward endof the lever will pre'ss'the knob downwardlyand will operate the machine to set staples in the usual manner. This lever may be operated in different ways. For instance, a handle may be pivoted at 31 between the sides of a fork 32 on the forward end of the lever. To the rear of the pivot this handle has a lug 32 which may on gage the bottom wall of the fork to limit movement of the handle in counter-clockwise direction and to in effect rigidly secure it to the lever for downward movement of the lever. If, however, it is desired to operate the lever by foot or power means, as will presently be described, this handle may be swung back out of the way as indicated in the dotted line position.

The lever 17, and therefore, the machine may be conveniently operated by power means or foot pedal. For this purpose a flexible connection 3%, such as a chain, is connected to the rear end of the lever 17 and passes over the guide pulley 19 and downwardly through an opening 35 in the bracket and base and is connected to a foot pedal mounted on the floor or any other suitable support. It will thus be apparent that by pressing downwardly on this pedal the front end of the lever 17 will be depressed and will operate the machine on the base the same as if it had been operated by the handle 30, or the flexible connection 34 may be connected to an eccentric or crank 87 mounted on a suitable shaft running in suitable supporting bearings 38 and driven by a belt 39 and pulley 40 from any suitable source of power, not shown, the foot pedal ell in this case being used to control a clutch 42 for connecting and disconnecting the eccentric or crank with or from the driving shaft. A spring 43 is provided to normally hold the lever 17 in its elevated position and keep the weight of this lever and the weight of the handle 30 off the knob 25. This spring is connected at its opposite ends to the lever and the upright 18 of the bracket.

It will thus be apparent any of these types of machines above mentioned which it is desired to operate more easily or with less tiring effect than the ordinary hand operation is merely seated with its feet in the proper openings on the base 10. This action will place the machine in proper position with relation to the operating lever 17 and then the machine may be operated either by the handle 30, the foot pedal 36 or the power drive as shown in Fig. 3, and this can be done without the necessity of making any mechanical connections whatever. The machine can, however, be as easily taken out of this device and carried to any other location in the ofiice where it is desirable to use it, and then after use can be as quickly and easily returned to the device, or any of the other of the standard machines of this type may be used in the device in the same manner. It will be apparent the machine does not have to be wmmw adjusted in position as its feet merely fit in the openings provided for it. It will also be obvious that the operating lever 17 may be arranged in numerous ways different from that shown, or the operating device of the machine proper may be operated by other mechanical arrangements than this lever. As this is a more or less universal operating mechanism for this type of machine it is not necessary to make special foot or power operating mechanism for each individual type of machine, and therefore, one type of operating device may be sold to be used with a number of different types of machines.

Having thus set forth the nature of my invention, what I claim is:
